The town drunk typically dwells in a small enough town that he is the only conspicuous alcoholic. Larger cities may have more than one, but this term appears to come from around the 17th century; in the stereotype, when a city grows large enough to house a sufficient mass of town drunks, the area where they congregate becomes known as Skid Row.

The town drunk may serve merely as a moral example and object lesson on the evils of drunkenness. This approach to the character is associated with the "temperance" movement, and peaked at the start of the twentieth century. The notorious Prohibition play Ten Nights in a Barroom portrays the inevitable fall into destitute drunkenness of a person who dared to take that "Fatal Glass of Beer", the title of another period drama working this vein. A town drunk who appears in Our Town by Thornton Wilder is perhaps the most often seen example of this version of the character.[1] Pap Finn in The Adventures of Huckleberry Finn is another famous example. In modern fiction, which tends to reflect the contemporary influences of the sobriety movement, the town drunk may get sober and set about revitalizing his life.[2]

In a similar vein, the town drunk may serve as a semi-comic proxy for the Wise Old Man. He may disrupt public meetings, either for comic effect, or by dispensing what proves to be wisdom in a garbled and comic form. Or, in this incarnation, the character may introduce the hero to some of the worldlier sorts of wisdom, as well as forming a contrast to his truly heroic character. One prototype for this version of the town drunk is supplied by Shakespeare's Falstaff, who appears in both parts of Henry IV and in The Merry Wives of Windsor. Another would be the drunk who appears in Team America: World Police at the low point of the film, where his drunken ramblings inspire the hero to save the world.

In the Family Guy episode "Peter's Two Dads", Peter is at first dismayed to discover that his Irish biological father, Mickey McFinnigan, is the town drunk. It turns out that in the town, being the town drunk is a respected and honored title.

The rake is another stock character associated with heavy drinking. However, the rake is invariably much younger than the town drunk, and the designation casts attention on sexual excess and spending money more than on strong drink.
